Question

A ) 2 ( x - 1 ) + 3 ( x - 2 ) = 2
B ) 8x = 2 ( 3x - 1 ) - 16
C ) 2 ( x - 3 ) = - 5 ( x + 4 )
D ) 6x - 7 ( 1 - x ) - ( 10x + 4 ) = 0
E ) x - ( x + 1 ) = 12 - ( 3x - 12 )
F ) 10 - ( 2x + 1 ) = 4 ( 2x + 3 )

Answer 1

a) 2x-2+3x-2=2

5x-3=2

5x=5

x= 1

b) 8x=6x-2-16

8x-6x=-18

2x=-18

x=-9

c) 2x-6=-5x-20

2x+5x=-20+6

7x=-14

x=-2

d) 6x-7+7x-10x-4=0

3x=11

x=11/3

e) x-x-1=12-3x+12

3x=27

x=9

f) 10-2x-1=8x+12

8x+2x=9-12

10x=-3

x=3/10

espero ter ajuado
